As of late there has been a few companies that have branded their PSUs with "SLI Certified" logos that weren't actually certified. We decided to see if this feature was accurate so we went over to the SLI Zone and were not able to find the Tuniq Potency 550W PSU in any list for any SLI setups. While I don't believe that an "SLI Certified" PSU is better than one that isn't actually certified, Tuniq either needs to remove the "Certified" sticker or make sure that NVIDIA puts it in their list. . .
